The song, recorded at Abbey Road studios, features a 70-strong choir and 66-piece orchestra - with vocals from lead Vaults signer Blythe Pepino.

But will it be able to reach the heights of the Christmas number one and hold onto the top spot in the run up to Christmas ?

The odds are looking good, and bookies William Hill are offering 10/1 odds for the song to be the Christmas number one single.

But British electronica trio Vaults will have to fend off the annual X Factor release and other number one contenders to win the festive fight.

Gareth Malone, famous for making choirs cool again with programmes like The Choir and The Naked Choir, is also good at pumping out the top tinsel tunes.

"The odds for the song have been as short as 6/1 to be Christmas number one and while we like the advert, we think it will struggle to hold off the inevitable X Factor and Gareth Malone push towards the big day," said William Hill spokesman Joe Crilly.

Malone took the Christmas charts by storm in 2011 when his Military Wives Choir soared to the top of the charts with their single Wherever You Are.

A Bridge Over You, sung by the Lewisham and Greenwich NHS Choir, also put Malone's choir at number one in December last year.

His previous successes have led bookies to cut his odds to 4/1, and with the musical maestro touring the country in his efforts to make the ultimate feel good Christmas album, his chances are looking good.

The annual X Factor Winner's Song is also a popular favourite, and took the top spot every year for a decade, with the exception of Joe McElderry.

But the John Lewis advert and the moving Vaults soundtrack have touched a chord with viewers.

The story follows Buster the bounce-loving dog, who watches as two foxes, a badger, a squirrel and even a hedgehog who has ventured out of hibernation enjoy a late-night bouncing session on the new trampoline.

Buster is stuck inside before he then gets a turn on Christmas morning.
